-fix for nanites traveling thousands of km, now should stay near facility

Thank you to BookBurner for fixes and updates to scripts.

-projection target scanning completely rewritten

-bunch of changes to avoid certain "stuck" scenarios

-better checks if components are available or not

-slightly better assembler queuing for missing components

-nanite slaving (primary + helpers when multiple nanites within 300m), basically allows players to have more upgrades than 8

-replaced couple of lists with hashsets to:
a) provide more randomization to how targets are selected
b) have better control over possible duplicate targets

-fix for projection repair/construction

-fix for the subpart emissive color error for compiling.
-main model changes (textures and geometry)

-added null check that was missing, may have been causing crashes and freezes

-changed the screen on the model to give help command /nanite help

- unchecking checkboxes will actually clean out target lists (better than !fixship or grinding the nanite facility down)
- some more thread safety added to the scan for mining targets
- some code simplification (no need to have separate protected and readable lists when lots of multithreading was removed)
- assembler queuing is finally not overproducing as crazy, it has a basic check to not queue items that are already in queue in some assemblers
- scanning for construction and projection targets should be a bit better and should lead to fewer cases where the nanite facility seems stucked on the blocks which it can't finish (different handling of ignore list which temporarily stores blocks that are not possible to build)
-nanite mining beacon will turn off when all ore in detection area is depleted, either change the ore selection or move the beacon to activate (this is expected behavior, beacon will periodically turn on and off to check to see if ore availability changes.

Thanks again to BookBurner for the updates!

-fix for the crash on more than one number entered into custom data of the mining beacon

-possible fix for the mining beacon not changing ore selection due to emptying out buffer of old ore queue
